FAQ: Optimize Features

  • +How is ZebraGuard Optimize different from a URL filtering software?

    URL filters only restrict access to known pornographic web sites. ZebraGuard protects users from any image displayed on a computer, regardless of its source. It detects images from all sources such as Internet, CD-ROM, DVD, hard drive, floppy disks, email messages, embedded documents and movies. Although the prime source of illicit materials, the downloading of pictures from the Internet is only one of many ways in which pornography is distributed, displayed and circulated without detection.

  • +How does ZebraGuard Optimize detect explicit image?

    ZebraGuard Optimize’s sophisticated, content-based, detection engine scans the computer screen, analyzes displayed images for skin tones, and checks for a range of criteria that are typically associated with pornographic images.

  • +What does ZebraGuard Optimize do when it detects explicit images?

    When ZebraGuard Optimize detects pornographic content displayed on a computer screen, it records the time and date of the event, logs the Web site address, and captures a thumbnail image of the computer screen. This information along with the name of the user’s computer is saved to a central log file. This process creates a complete audit trail which the
    management can use to enforce company policy.

  • +Can I customise ZebraGuard Optimize monitoring level?

    You can customize ZebraGuard Optimize’s monitoring levels to suit your organization’s requirements. ZebraGuard Optimize offers three modes of operation that determine how a client PC is monitored. They are Passive Mode, Active Warn Mode, and Active Lock Mode

    – In Passive mode, the system detects and monitors suspected pornographic content silently. In Active Warn mode, the system displays a warning message that advises users that they might be watching pornographic content, which is not
    allowed in the organization’s computer facilities.

    -The most sensitive mode of operation is Active Lock. Active Lock blocks offending images immediately and locks the PC until a supervisor reactivates the machine. Active Lock mode requires the more management supervision. This extra supervision requires responding to calls for supervisor help to unlock computer screens. These calls often come from users not even remotely involved with surfing porno sites.

    -The Active Lock mode is therefore not recommended for corporate, government, or large enterprise use. You can
    manage your enterprise networks effectively by choosing either the Passive mode or the Active Warn mode. Active Lock is ideal in situations where you have young children surfing the Internet and strict supervision is required. In this scenario, teachers or parents are at the ready to unlock machines that could expose children to unwanted words and images.

  • +Can ZebraGuard Optimize block pornographic content from being displayed on the PC Screen?

    ZebraGuard Optimize offers multiple options to prevent pornographic content from being displayed on the PC screen. These
    options allow you to set the level of protection that is right for you.
    For example, Active Lock Mode blocks offending images, locks the machine, and logs the event in a central log file. The locked machine can’t be reactivated until a supervisor unlocks it. Active Warn Mode detects offending images and sends a warning message to the user when pornographic material is detected.

  • +Will ZebraGuard Optimize flag images that are not explicit?

    Depending on the threshold level you set for the system, ZebraGuard Optimize will flag images that are not explicit. This is
    because the ZebraGuard’s detection engine is designed to identify flesh tones, and as flesh tones can appear in almost any image, the system does its job and flags the image. However, ZebraGuard Optimize applies advanced algorithms and
    analytics to reduce this risk, so the incidence of unnecessary flagged images is kept to a minimum. You can adjust the
    sensitivity threshold on the Image Detection tab of the Profile Properties window to suit your company policy.

  • +Can simply having ZebraGuard Optimize installed on a computer serve as a deterrent?

    Yes, because you can display a ZebraGuard Optimize icon in the Windows Task Bar of each personal computer. This icon is a
    visible and permanent reminder to users tempted to view pornographic content.

  • +How to scan the video and images on a specific PC?

    ZebraGuard Optimize Remote Administration application allows you to individually scan the hard drive of each client for any videos and images present in the hard disk. Since the scan drive process requires considerable system resources it is

  • +How to customise your ZebraGuard Optimize acceptable use policy?

    ZebraGuard Optimize enables the administrator to ensure users are aware of the computer usage policy that the organization might have in place. This is done by displaying a message when the user logs on to the client PC.
